JOURNAL-BEARING.

Fi-PECIFICATION forming part of Letters Patent No. 352,685, datedNovember 16, 1886.

To aZZ whom it may concern:

Be it known that we, WILLIAM A. FRANK and THOMAS \VICKS, citizens of theUnited States, residing at Final, in the county of Pinal and Territoryof Arizona, have invented journal-bearings.

It is a fact well known to the operators of machinery that in that classof journal-bearings provided with removable caps the oil works out fromthe bearing at the parting of the box and cap, however tight the jointmay be. In the class of machinery with which we are acquainted in miningthe caps of the bearings are quite loose, leaving an open joint, and wehave observed that for some time after cleaning these joints the bearingdoes not heat so quickly as when the joints are filled with dirt. Wetherefore conclude that so long as the lubricant remains fluid in thejoint it floats, particles of dirt and fine grit out from the bearing;but when so much dirt gathers in the joint that it dries in a cake alongthe hearing it closes the latter, and then the grit, having no escapefrom the bearing, produces friction-and heat. be kept lubricated alongthe cap and. box

,5 joint, the grit will continue to work out; and

the object of theinvention is to provide means whereby oil, thickgrease,or any other suitable lubricant may be distributed automaticallythroughout the length of journal-bearings.

To this end the invention consists in grooves formed in bearings, ashereinafter described and claimed, reference being had totheaccompanying drawings, in which- Figure l is a perspective view of thelower half of a journal-bearing, showing our invention. Fig. '2 is atransverse section of a complete bearing.

Now, if the bearing can A represents the lower half of the bearing, Bthe upper half or cap, and (3 the bore in which the journal is designedto revolve.

In constructing this hearing we form grooves 11 therein longitudinallywith the shaft. These grooves are most economically formed by casting'slanting faces cat the parting of the hearing; but they may be formed inbearings already made by cutting away the corners and leaving theslanting face a, and thus forming groove 1;. When the journal is torevolve in only one direction, as shown by the arrow 0, the best resultis produced. by leaving the corners 01 full, as shown in Fig. 2, andcutting or casting the adjacent cornersa slanting. The sharp corner dhas a tendency to scrape away from the journal any grit or other foreignsubstance which might otherwise cut creases and rapidly wear away boththe journal and bearing, and to hold the said foreign substance in thegroove, where it may be readily cleaned away by removing the cap orupper half of the bearing; but the main service of these grooves is togather the oil, which is generally poured in at a single centraloil-hole, e, at the top'of the hearing as it comes around on thejournal, and flow it each way toward the ends of the bearing until allparts are equally oiled. The kind of oil or grease used makes nodifference with this device.

To make our oil-distributers more complete we form oil-holes F throughthe cap of the bearing directly into the grooves. By this means ofintroducing fresh oil directly into the groove at the cap-joint all gritand gummy matter may be dissolved and forced out at the end of thebearing and through the parting without the trouble of removing the cap.

If the hole F be dispensed with and oil be introduced at the usual pointthrough hole e in the cap, the oil-gr0oves b will accumulate the oil andgrit, which will work out at the parting for a much longer time beforeclogging the parting than if there were no groove at the joint to hold abody of oil. If oil be introduced to the hearing at any point, it willbe gathered and distributed along the hearing by these grooves, and willcontinue to be used over and over by the journal, while the grit attheir joint and provided with an oil-hole, scraped fromthejournalwillcontinually crowd substantially as shown and described.
